Examples Of Different Intermittent Fasting Schedules
If youre considering giving fasting a shot, there are a few different options for working it into your lifestyle.
Daily Intermittent Fasting
Most of the time, I follow the Leangains model of intermittent fasting, which uses a 16hour fast followed by an 8hour eating period. This model of daily intermittent fasting was popularized by Martin Berkhan of Leangains.com, which is where the name originated.
It doesn’t matter when you start your 8hour eating period. You can start at 8am and stop at 4pm. Or you start at 2pm and stop at 10pm. Do whatever works for you. I tend to find that eating around 1pm and 8pm works well because those times allow me to eat lunch and dinner with friends and family. Breakfast is typically a meal that I eat on my own, so skipping it isn’t a big deal.
Because daily intermittent fasting is done every day it becomes very easy to get into the habit of eating on this schedule. Right now, you’re probably eating around the same time every day without thinking about it. Well, with daily intermittent fasting it’s the same thing, you just learn to not eat at certain times, which is remarkably easy.
Weekly Intermittent Fasting
One of the best ways to get started with intermittent fasting is to do it once per week or once per month. The occasional fast has been shown to lead to many of the benefits of fasting we’ve already talked about, so even if you don’t use it to cut down on calories consistently there are still many other health benefits of fasting.
Cons Of Intermittent Fasting
Intermittent fasting is one way to regulate your calorie intake and work toward improving your metabolic health.
Though the eating pattern can certainly be part of a healthy diet, it will likely take some adjusting to in the beginning. Plus, simply put, intermittent fasting is not right for everyone.
Here are a few downsides you could encounter when first trying intermittent fasting.
Can I Exercise While Fasting And When Is The Best Timing
Yes! Its generally safe to exercise while fasted. However, talk to your physician if you have diabetes or have experienced hypoglycemia during or after fasted exercise.
People practicing alternate day fasting choose to exercise on fasted days as often as on their feeding days. However, when approaching the end of a long fast you may want to stick to light to moderate physical activity.
There arent necessarily best practices for exercise timing with fasting. However, theres evidence that fasted exercise can send you into deeper ketosis more quickly. Light exercise right before or after you eat can also help your body soak up glucose more quickly. High intensity exercise can even raise your blood glucose levels temporarily as your muscles release glycogen and your liver produces new glucose, which could leave you feeling uplifted during a prolonged fast. There are many ways to combine fasting with exercise. Learn more here.

Intermittent fasting is an eating plan that switches between fasting and eating on a regular schedule. It involves a pattern where you cycle between periods of eating and fasting. It is also an umbrella term for various meal timing schedules that cycle between voluntary fasting and non fasting over a given period.
Intermittent fasting does not say anything about which foods to eat but rather deals with when you should eat them.
There are several different fasting methods, all of which split the day or week into eating periods and fasting periods. Going without food for a number of hours each day or taking just one meal a couple of days a week can help your body burn fat.

Fast For 12 Hours A Day
The rules for this diet are simple. A person needs to decide on and adhere to a 12-hour fasting window every day.
According to some researchers, fasting for 1016 hours can cause the body to turn its fat stores into energy, which releases ketones into the bloodstream. This should encourage weight loss.
This type of intermittent fasting plan may be a good option for beginners. This is because the fasting window is relatively small, much of the fasting occurs during sleep, and the person can consume the same number of calories each day.
The easiest way to do the 12-hour fast is to include the period of sleep in the fasting window.
For example, a person could choose to fast between 7 p.m. and 7 a.m. They would need to finish their dinner before 7 p.m. and wait until 7 a.m. to eat breakfast but would be asleep for much of the time in between.

How Does The 8 Hour Diet Work
The 8 hour diet works in the following ways:
- Stimulates The Function Of The Mitochondria Mitochondria are cell organelles that convert glucose to usable energy . Fasting for 16 hours helps stimulate the mitochondria and reduces the level of intracellular damage caused by a poor diet ,
- Uses Up Glycogen And Fat Stores Glucose is converted into glycogen and stored in your muscles and liver. In a fasted state, your body first uses up glycogen for fuel and then gains access to fat stores .
The 8 hour diet teaches you how to trigger the furnace in your body that burns fat while you sleep so that the flab can get stripped away right from the moment you wake up.
- Burns The Calories You Consume According to David Zinczenko and Peter Moore, the authors of The 8 Hour Diet, modern lifestyles involve grazing or eating around the clock, which does not give your body sufficient time to burn all the calories that it is required to.
While you are fasting, your body gets the chance to reset itself and digest food. This allows your body to process nutrients and eliminates toxins effectively.
- Keeps You Satiated Most diets are restrictive. From portion control to caloric restriction, there are various terms and conditions that the dieter needs to follow. The 8 hour diet takes the pressure off a traditional diet.
Having the freedom to eat everything within an 8 hour window keeps your taste buds alive and prevents boredom. Thats why it is sustainable.
What Is Intermittent Fasting 1: 8
Intermittent fasting 16:8 is where you fast or abstain from eating for 16 hours, and only consume food within an eight-hour window.
Fasting has gained popularity in recent years in the health and fitness world, says Dr Mahmud Kara, creator of KaraMD . There are many different types of fasting diets that people can follow according to their own health needs or goals. The eating style itself was founded by Jason Fung, MD, and in its simplest form fasting occurs when you alternate between periods of eating and not eating.
But what does fasting do to the body? When we consume food, our bloodstream is suddenly bombarded with nutrients in the form of simple carbs, amino acids and fats depending on the meal consumed,” says Dr Kara.
This forces the body into a highly metabolic state that in and of itself requires a lot of energy. Constant eating, even if you eat good carbs, fat and protein, puts our body, and our cells specifically, in a state of being signaled to work for example, to remove digestive byproducts and metabolize nutrients.
Fasting gives our cells a chance to rest and repair. Because fasting plays an essential role in giving the body and its systems a chance to reset, recent studies including a review published in the New England Journal of Medicine have suggested it can ultimately help in a variety of health areas: reducing inflammation, stabilizing blood sugar levels, improving weight management and reducing the risk for chronic disease.

* Can Prove To Be A Long
Intermittent fasting can seem intimidating at first, but it is less complicated than it seems. This method simplifies your day since, unlike other diet plans, you dont have to plan a lot of meals.
Alongside, it doesnt require you to keep a close check on the macros or calorie intake, eating or eliminating certain foods that you otherwise gorge on.
Whens The Best Time To Exercise On If
Honestly, the best workout is one that gets done. Work out when it works best for you and youll still reap the benefits.
However, there are two other schools of thought on working out while fasting.
The first is that working out while fasted helps you to burn more of your stored body fat. Some small studies support this theory, while others have found that fasting doesnt make a difference in fat burning.
If weight loss is your goal, this may be an approach you want to try out.
Alternatively, trying to work out on a totally empty stomach may leave you feeling yucky.
Working out during your eating window may provide more energy to help you power through your workout. If youre doing endurance exercise, its probably better to go with this approach and have a balanced meal before you get after it.

Jennifer Aniston Said She Noticed A Big Difference When She Went On The Plan So We Ran It By Nutrition Experts
Let’s face it, we all want the Jennifer Aniston glow. Does this woman ever not look like she’s just walked out of a wellness retreat? Clearly, she knows a thing or two about health and well-being, and she’s finally sharing some of her secrets.
In an interview with UK magazine Radio Times during the promo trail for her Apple TV+ show, The Morning Show, Aniston revealed that she’s a big fan of intermittent fasting, particularly a version called the 16:8 diet.
“I do intermittent fasting, so no food in the morning. I noticed a big difference in going without solid food for 16 hours,” said Aniston, per CNBC.
Aniston’s preferred way of intermittent fasting limits her eating time window to eight hours per day, while fasting for the other 16 hours, Tanya B. Freirich, MS, RD, CDN, New York-based nutritionist and registered dietitian, told Health. Other types of intermittent fasting diets include the 5:2 diet, which involves fasting for two nonconsecutive days each week and eating without restrictions on the other five days. There’s also the OMADor one meal a daydiet.
Intermittent fasting is rather popular, and it’s easy to see why. For starters, there’s no prescribed calorie limit, which means no crunching numbers and relying on calorie counting guides before eating. But what else is involved in the 16:8 eating plan and similar fasts, and are they actually safe? Here’s what nutrition experts have to say.

Any Intermittent Fasting Method Can Work
The best fasting method is the one you can stick with until you reach your goal.
Any intermittent fasting method can work for you. And to be honest any diet can work also. Intermittent fasting is one that suit many people due to flexibility and ease of implementation. Which makes it easier to stick with in the long run.
But any diet can work for weight loss. Be it Intermittent Fasting, Keto, Paleo, Vegan or Weight Watchers they all can work.
This is because human physiology and weight loss works the same for every human being.
And all diets and eating systems for weight lsos work on the same major principle of:
*Calories VS Calories Out*
Eat less calories than you burn consistently over weeks and months and you will reach all of your weight loss goals.
Similarly all intermittent fasting methods work in the same way.
Any of them CAN work for you.
But the best one for you is the one you can stick with consistently over time.
This means picking the fasting method that integrates into your lifestyle well.

Potential Drawback: High Stress Hormones
With the shift from carbohydrate to fat metabolism comes another type of shift: a hormonal one.
As your body gets used to burning fat for fuel, it may utilize stress hormones like cortisol to liberate amino acids and fats from your reserves. This process can feel stressful until your body becomes efficient at fat burning, at which point cortisol levels return to normal.
What Happens When You Change Your 16/8 Eating Window
This is a tough question to answer because to the best of our knowledge, there hasnât been any studies that have investigated this. However, based on what we just described about the circadian rhythm, you are probably not reaping all of the benefits this diet can offer you.
If you are changing times by going outside of your window by a small amount, maybe a half hour or less, or if you go way outside your window every once in a while, you are probably fine. But if your eating window changes by more than 30 minutes and this happens regularly, you may want to rethink your chosen eating window.
The way you mitigate disease risk through the 16/8 diet is by eating in a timeframe that aligns with your circadian rhythm and when pathways related to metabolism and digestion are upregulated.
Consistency is key. Changing your 16/8 eating window regularly isnât helping your health.

What Are The Drawbacks Of Following The 1: 8 Diet
While the 16:8 diet seems like a great way to drop weight fast, it does have some cons. Sarah Mirkin, RD, author of Fill Your Plate, Lose the Weight, a 21-day meal plan designed to help women over 40 lose weight, says, “I think that it limits food intake to such a small window of time that it’s difficult for someone to meet their nutritional needs.”
Indeed, fasting for a long period of time probably means you’re not able to enjoy three full meals with snacks each day. Whether you’re skipping breakfast or dinner, missing a meal always results in not receiving adequate nutrients. And since the 16:8 diet gives you license to eat whatever you want, you might be tempted to fill up only on fatty, processed foods, especially if you’re feeling ravenous. Hunger can also clout your better judgment and lead you to binge eat as well. “Studies show that the majority of people are not able to sustain it for very long and oftentimes end up binging on unhealthy foods, causing weight gain,” Mirkin says. Other drawbacks of 16: 8 fasting include poor sleep, muscle mass loss , disordered/binge eating, weakness, nausea, and fatigue, Mirkin says.
Can You Give Me An Example Of A Good Intermittent Fasting Meal Plan For 1500 1700 Or 1800 Calories
I could tell you exact things to eat, but I think you can take any foods you love and make them fit into your intermittent fasting lifestyle.
A good rule of thumb is to take your daily calorie goal and split it up like this:
- 20% of calories to break the fast
- 60% of calories for dinner
- 20% of calories for dessert or before-bed snack
Remember, since youre skipping breakfast, you only have to make it a few hours after breaking the fast until its time for a big dinner feast.
You can alter the percentages a little bit as needed.
For example, I prefer to have a few more calories at lunch so I can eat a respectable meal with my wife and daughter, and fewer calories before bed.
Some people prefer a bigger dinner, or more snacks throughout the day.
Do what works for you. But in general, the goal is to have a large and filling dinner and split the rest of your calories as you see fit.

Is Intermittent Fasting Safe
Some people try intermitting fasting for weight management, and others use the method to address chronic conditions such as irritable bowel syndrome, high cholesterol or arthritis. But intermittent fasting isnt for everyone.
Williams stresses that before you try intermittent fasting , you should check in with your primary care practitioner first. Some people should steer clear of trying intermittent fasting:
- Children and teens under age 18.
- Women who are pregnant or breastfeeding.
- People with diabetes or blood sugar problems.
- Those with a history of eating disorders.
But, Williams says, people not in these categories who can do intermittent fasting safely can continue the regimen indefinitely. It can be a lifestyle change, she says, and one with benefits.
Keep in mind that intermittent fasting may have different effects on different people. Talk to your doctor if you start experiencing unusual anxiety, headaches, nausea or other symptoms after you start intermittent fasting.
